Custom Pega Function - Add three Months to Date

 Hi,

In this blog we will see now to create our own custom function for adding 3 months to Date.


Before Creating our function we need to create Library (Data Instance Rule). 


Go to Records --> Technical --> Library  (Right click create)


Library Name = ArtLib

RuleSet Name = Art


In Packages Tab, inside Java packages to Include


1) java.io.*;


2) java.util.*;


3) javax.xml.transform.*;


4) javax.xml.transform.stream.*;


5) java.time.*;


6) java.time.format.*;


7) java.time.temporal.*;


{checked} Library ready to compiled?


Now,


Go to Records --> Technical --> Function --> Right Click Create

Function Name = AddthreeMonthsToStringDate-(String)


Parameters (TAB)

Input parameters

StrDate         String  (Java type)

 

Output

Java data type = String

Pega type = Text


Java (TAB)


LocalDate local_date_1;

LocalDate  local_date_2;

DateTimeFormatter formatter_1 = DateTimeFormatter.ofPattern("yyyyMMdd");

String str_date_1 = StrDate;

Local_date_1 = LocalDate.parse(str_date_1,formatter_1);

local_date_2 = local_date_1.plusMonths(3);

String str = local_date_2.toString();

String result = str.replace("-","");

return result


To test above created function, Open Data Transform or Activity and use expression builder


AddthreeMonthToStringDate("20200123")


Result = 20200423

pyForEachCount holds the current iteration number. You can examine (but not alter) this value in the step.                 When processing the For loop or iterating over a Value List or Page List property, the parameter param.pyForEachCount holds the current iteration number.  You can examine (but not alter) this value in the step. For example, to iterate only over the first ten  pages or values, you can exit the iteration when pyForEachCount is greater than 10. In below example we will see how we can use pyForEachCount in data transform and set value in .pxResults.
